We don't know if freebitco.in has done something or if it was the hackers who removed the malicious code to calm us down, but they will come back.
Seeing that Freebitco.in has neither responded to any email, nor has it given any explanation nor does it appear anywhere, I believe it was the second option and I also believe that there will be no refund. We have been robbed and have lost our funds.
trust in freebitco.in = 0%

Your attitude and the attitude of all those who have suffered financial loss is completely logical and I agree that the reputation of this service is quite damaged after everything that happened. However, I think that they should be given a chance to show that they are still serious about what they are doing.

We recently had an example where one user received his deposit after 8 months if I am not mistaken, so although it is difficult to find justification for such a delay in solving the problem, we should not completely reject the possibility that freebitco will compensate all those who were victims of malicious scripts.

I agree, it's early days in Freebitco time and I've never seen a case so far where the fault has been found to be with Freebitco and the affected user has not been recompensed.

You're not mistaken about the case you mention, it was a deposit issue, the poor guy really went through it and understandably came to a similar conclusion that his funds were lost.

The malicious code is gone. But the lost funds were not reimbursed to us and it seems they are not going to, they just threw us

That rogue jquery cdn include is some serious obfuscation. It doesn't look like that one is easy to unobfuscate, It is an enormous function built by lots of mini functions referencing memory addresses, very hard to follow. It would take me hours to decipher all that.

It's gone!

I looked through the malicious JS code. It seems to be targetting user id 31898443 specifically (unless a different ID is loaded based on the url parameters used to load the js from the cashtravel site.

It appears then to hit https://bitwrecken.com/?action=new&id=31898443 to get the new / rogue deposit address. Presumably this is done so the attackers can cycle through various different rogue deposit addresses, or even randomise them.

There is a then a html element called main_deposit_address which is replaced by the value retrieved from the bitwrecken.com site

The script is actually rather simple in how it works, nothing complicated going on.

The worrying part, is how the attackers were able to embed this into the freebitco.in site and whether it has affected all users. It feels like those who clicked the advanced tracking button in the referral page may be the ones who were hit, but not seen any confirmation of this.

Thankyou for your analysis.

What do you make of this

OK, so that people no longer have doubts about how the address is being changed when withdrawing funds. At the end of the video, watch carefully how my output address was changed!!! I hope no one else will say that we are deceiving you and the site is not hacked!
https://dropmefiles.com/56V5d

Update!!:
After I posted the video with the substitution of the withdrawal address, an hour later I tried to withdraw funds again and surprisingly my address did not change and the withdrawal went to the correct address! Is it a coincidence??? Or are hackers monitoring this forum topic?

It appears you do not have 2FA enabled which is why you received a payment request confirmation email and were therefore able to abort the withdrawal by not clicking the confirmation link in the email.

I have disabled 2FA for this reason.

Thankyou for the video. Much appreciated.

I also turned off 2fa for this reason, but! there is one important caveat, if you withdraw funds to an address linked to an fbc account, then an email with a confirmation link will not be sent. Therefore, you need to make a withdrawal to an address that is not linked to the account!

Thanks for the additional information.

It would seem then that the safest course of action is to turn off 2FA and generate a new Bitcoin wallet address. And of course confirming the address before clicking the confirmation link in the email.

@BayAreaCoins

Someone mentioned in another simular topic that the link to the malicious script was somehow hidden in the advanced tracking using tags button code on the freebitco.in site.

https://bitcointalksearch.org/topic/m.64033700

I actually did click that button days prior to the attack on my account.

Food for thought.

That's when I made the mistake of enabling 2FA

Even with 2fa, my default profile address never changed...

Same here, my profile address never changed.

I didn't even attempt a withdrawal.

The hackers triggered the withdrawal seconds after the prize money was credited to my account, and somehow they managed to bypass my profile address.

Ouch, gotcha... Takes the sting out of me at least trying to get process a little less stingy... *sigh*

They must have been able to solve our 2fa "upgrade" for us... how kind.

Initially I didn't make a withdrawal.

I just opened freebitcoin to check my balance just as you did.

I wonder if this script can send a withdrawal request or change the withdrawal address though. Since it has an access to the client side, it can do whatever it wants. (From your side)

Yes, it can do both. An unauthorised withdrawal was initiated on my account. And it was able to bypass my profile address.

Shiet. Now we all can panic.

TheQuin where the hell are you man your establishment has caught FIRE!

Absolutely!

If you have 2FA enabled you won't get a payment request confirmation email from freebitco.in

What you will get is a payment sent confirmation email.

The attackers targeted the bigger fish. This time...

If the attackers are able to bypass the 2FA security and to initiate withdrawals whenever they want why you are the only user reporting it till now? They would have no reason to wait before withdrawing as much funds as they can, so I think many people would already be here complaining about random withdrawals happening spontaneously. That's why your claim is a little bit surprising. Are you sure no one living with you, has been able to steal your funds? If yes, are you sure your 2FA device is safe and hasn't been compromised too?

The OP listed points 1-8 above

My situation and reaction was almost identical. Obviously the amount I won was different. The unknown address was also different.

I didn't say, "the attackers are able to bypass the 2FA security..."

I said they were able to initiate an unauthorised withdrawal, bypass my default profile address and insert an unknown Bitcoin address.

It's important to note that this happened prior to enabling 2FA.

After I enabled 2FA, I initiated an authorised withdrawal. The attackers hijacked this withdrawal.

What I said in relation to 2FA was you won't receive a payment request confirmation if 2FA is enabled.

So, having 2FA enabled therefore does work to the attackers advantage.

Maybe something got lost in the translation.

Yeah.

It's not safe to deposit. The attackers can change the destination address.

It's not safe to withdraw. For the same reason.

It's not safe to stand idly by and do nothing. The attackers can initiate a withdrawal and overwrite the profile adress

The attackers know that their attack was successful.
I would expect them to target any user with a balance above the minimum withdrawal threshold next.

The attackers also know that the vulnerability that they are exploiting will sooner or later be patched

If you can get your coins out now before the attackers make their next move...

It is not safe and there is more than one problem. There has been talk of a cashtravel script that those of us affected have had but now it no longer appears and even so, the deposit addresses are fake (and it is not possible to change it) so any withdrawal can go to any unknown address.

This is the address where all my funds were stolen and still is the Deposit address when i click the Deposit button: 144p3SroEwDs1rdMmBqkCKHLpQ2TUCH3Li.

My real Diposit address does not even appear in the old ones inside the window.

I have made my account available to freebitco.in by email for investigation but they do not respond to any email. I hope they are doing something even if it is silent.

By the moment, of couse I cannot do anything in freebitco.in and i am recomending not using the page.
